C) it is made up of carbon, hydrogen, and oxygen
D) it is a compound made of twenty-four total atoms of three different elements
they are both right but I would go with D
Answer:
Rate of Ar= 1.65 x mol/h
Explanation:
Here we'll use Graham's Law where
R= rate of effusion and M= molar mass
Let's plug in what we know.
You could switch them where Xe is M1 (on the bottom) instead of M2, but I find it easier when the unknown is R1, where it acts like a whole number. It makes the algebra part of the equation easier.
Let's solve for R1.
R1= 1.089 x
R1= 1.65 x mol/h
Their average speed during the trip is 53 km/ hr approximately
Explanation: The family traveled 80 km/hr for an hour and then trabeled 40 km/ hr for 2 hours. So they traveled 80 km in one hour then 80 km in the next 2 hours. Total they traveled 160 km in 3 hours.
Average speed = distance traveled/ taken time
= 160/3 = 53.33
